In this chapter, we'll expand on the basics of zsh while focusing on aliases, one of the most time-saving features available. We'll take a closer look at how aliases work and learn to replace long, boring commands with our own short versions and automate the whole process within the startup files. We'll then move on to brace expansion, in order to avoid typing extra keystrokes whenever we can. Instead of typing the same things over again, we'll learn how to work with zsh's history and history expansion mechanisms and incorporate these new features into our workflow.
